Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation chair technology, specifically relating to a rehabilitation chair for patients after hip fracture surgery. Background Technology

[0002] For elderly patients undergoing surgery for hip fractures, the core of rehabilitation in the early postoperative stage is to enable them to get out of bed and move around as early as possible. The progression of mobility is as follows: sitting up in bed → sitting up at the bedside → sitting up in bed → standing up in bed → walking in bed, gradually increasing the necessary tools, including a bed, chair, and walking aids. However, currently, patients primarily adopt a sitting / sitting-up position in bed or use walking aids to stand and walk in the early postoperative period.

[0003] However, under the concept of rapid rehabilitation, patients need to get out of bed and move around early after surgery. But the time to get out of bed and walk varies depending on the type of hip fracture surgery. Therefore, rehabilitation chairs are used to facilitate the transition from bed rest to walking, with the aim of reducing complications during bed rest for patients with hip surgery. Also, since the hip flexion angle of patients with femoral-tibial fractures cannot exceed 90 degrees after surgery, and the existing rehabilitation chairs have limited functions, they cannot meet the needs of such patients. Therefore, a rehabilitation chair for patients after hip fracture surgery is designed to overcome the above-mentioned technical deficiencies. Utility Model Content

[0024] This specific embodiment is a rehabilitation chair for patients after hip fracture surgery, and its structural diagram is shown below. Figures 1-6As shown, the chair includes a chair frame 1, with armrests 2 fixedly connected to both sides of the top of the chair frame 1, and a back panel 6 movably connected to the rear of the top of the chair frame 1. The rear end of the armrests 2 is integrally formed with an arc-shaped part 201, and a connecting tube 202 is fixedly connected between the ends of the two arc-shaped parts 201 away from the armrests 2. An angle adjustment component 4 is provided between the two arc-shaped parts 201, and a height adjustment component 5 is provided at the bottom of the chair frame 1. The seat surface and the back panel 6 of the chair frame 1 are provided with a seat cushion and a backrest cushion.

[0025] In actual use, first adjust the height adjustment component 5 to the lowest position to facilitate helping the patient onto the seat of the chair frame 1. The armrest 2 can support the patient's arms. Since the hip flexion angle of a patient with a femoral neck fracture cannot exceed 90 degrees after surgery, the height adjustment component 5 can raise or lower the patient's feet. At the same time, the angle adjustment component 4 can adjust the tilt angle of the backrest 6 to meet comfort and adjust the hip flexion angle.

[0026] In addition, a dining board 3 is connected to the upper outer side of the right armrest 2 with damping hinge. The two arc-shaped parts 201 are provided with arc-shaped grooves in the middle of the side that are close to each other. The arc-shaped grooves are connected to the connecting cylinder 202. Self-locking universal wheels 101 are installed at the bottom of the uprights of the chair frame 1. The dining board 3 can be folded forward and upward by hinge, so that the dining board 3 is placed horizontally on the armrest 2, which makes it convenient for the patient to eat.

[0027] In addition, the angle adjustment component 4 includes two arc-shaped blocks 401 and a round rod 404 adapted to the arc-shaped groove. The arc-shaped blocks 401 are slidably connected in the arc-shaped groove. One end of the round rod 404 is rotatably connected to the inner wall of the right end of the arc-shaped groove through a bearing. The other end of the round rod 404 passes through the arc-shaped groove on the left side through a rotating shaft and extends to the outside, where a rotating wheel 406 is fixedly connected. The rotating wheel 406 has a certain damping when it drives the round rod 404 to rotate through the rotating shaft, preventing accidental collision with the rotating wheel 406. The arc of the arc-shaped blocks 401 and the arc of the arc-shaped groove are equal to the arc of the arc-shaped part 201, so that the arc-shaped blocks 401 can slide smoothly in the arc-shaped groove.

[0028] In addition, the rear end of the arc-shaped block 401 is fixedly connected to a threaded block 402, and the connecting rod 404 is provided with external threads 405 in opposite directions. The two threaded blocks 402 are respectively threaded onto the corresponding external threads 405. The ends of the two arc-shaped blocks 401 that are close to each other are provided with multiple slots 403. When the round rod 404 rotates, it can drive the two threaded blocks 402 on it to move closer to each other or further away from each other, thereby making the arc-shaped block 401 closer to or further away from the back plate 6.

[0029] In addition, multiple slots 403 are evenly distributed. The bottom end of the back panel 6 is rotatably connected to the rear top of the chair frame 1 via a pivot. Insert blocks 601 that are slidably connected to the slots 403 are fixedly connected to the middle of both sides of the back panel 6. The center of the arc-shaped part 201 and the hinge point at the bottom of the back panel 6 are concentric. The back panel 6 is in contact with the connecting cylinder 202. When it is necessary to adjust the angle of the back panel 6, the two ends of the round rod 404 can be driven away from each other by rotating the wheel 406, thereby moving the two arc-shaped blocks 401 away from each other and disengaging the insert block 601 from the slot 403. Then, the angle of the back panel 6 can be adjusted. Afterward, the wheel 406 can be flipped to bring the two arc-shaped blocks 401 closer together and insert the insert block 601 into the appropriate slot 403, thereby limiting and fixing the back panel 6.

[0030] In addition, the height adjustment assembly 5 includes a mounting box 503, which is located below the chair frame 1. Two connecting rods 502 fix two U-shaped plates 501 to the center of each side of the mounting box 503. The open ends of the four U-shaped plates 501 are slidably connected to the corresponding support pillars of the chair frame 1. A screw 504 is rotatably connected to the center of the inner bottom wall of the mounting box 503 via a bearing. The top of the screw 504 passes through the inner top wall of the mounting box 503 via a rotating shaft and extends upwards to be fixedly connected to a first bevel gear 509. Guide rods 505 are slidably connected inside the mounting box 503 and on both sides of the screw 504. The bottom of each of the 5 rods penetrates the inner bottom wall of the mounting box 503 and extends downwards to be fixedly connected to the bottom plate 506. The top ends of the two guide rods 505 are connected to the top plate 507. The middle part of the top plate 507 is threadedly connected to the screw 504 through the threaded sleeve 508. When the screw 504 rotates, it can drive the top plate 507 to move up and down through the threaded sleeve 508. The top plate 507 drives the guide rods 505 to move up and down, and at the same time, the guide rods 505 drive the bottom plate 506 to move up and down. When not in use, the mounting box 503 can be pushed backwards to move the U-shaped plate 501 backwards on the support of the chair frame 1, thereby moving the bottom plate 506 backwards for storage.

[0031] In addition, a foot pedal 514 is fixedly connected to the front end of the base plate 506. A second bevel gear 510 is meshed with the left side of the first bevel gear 509. A rotating rod 511 is fixedly connected to the middle of the end of the second bevel gear 510 away from the first bevel gear 509, and the rotating rod 511 is rotatably connected to the top of the mounting box 503 through the mounting bracket. A turntable 512 is fixedly connected to the end of the rotating rod 511 away from the second bevel gear 510. Limit nuts 513 are threaded into the top ends of the two U-shaped plates 501 on the left side. The bottom end of the nut 513 contacts the support column of the chair frame 1; the turntable 512 can drive the rotating rod 511 to rotate forward and backward, the rotating rod 511 drives the second bevel gear 510 to rotate and mesh with the first bevel gear 509, the first bevel gear 509 drives the screw 504 to rotate forward and backward through the rotating shaft, thereby causing the base plate 506 to move up and down, the base plate 506 drives the foot pedal 514 to move up and down, thereby raising the patient's feet; the limiting nut 513 can limit the position of the U-shaped plate 501.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
